Q: What does code P2A1A mean?

Injection Pump Fuel Metering Control E (Cam/Rotor/Injector). P2A1A indicates that the engine control module (ECM) has detected an out-of-range condition in the electrical circuit for the fuel metering control actuator labeled 'E' on the injection pump, which may be a cam, rotor, or injector-mounted component depending on the pump design. The ECM monitors the actuator's command signal and feedback voltage, and it sets this code when the actual current or position does not match the commanded value within a calibrated window.
